Error after activation

[mausi121]

After activation I get the following error:

mepages/u16211/anhaenger.craftmax.com/wp-content/plugins/woocommerce-external-product-embed-master/vendor/autoload.php): failed to open stream: No such file or directory in /homepages/u16211/anhaenger.craftmax.com/wp-content/plugins/woocommerce-external-product-embed-master/woocommerce-external-product-embed.php on line 54

Warning: include_once(): Failed opening '/homepages/u16211/anhaenger.craftmax.com/wp-content/plugins/woocommerce-external-product-embed-master/vendor/autoload.php' for inclusion (include_path='.:/vrmd/webserver/php-7.3.26/lib/php') in /homepages/u16211/anhaenger.craftmax.com/wp-content/plugins/woocommerce-external-product-embed-master/woocommerce-external-product-embed.php on line 54

What can I do?
